vocabulary exercise for deliberate learning. Nevertheless, students can still learn the vocabulary in the textbook incidentally if they receive more input from other
sources and have opportunities to learn the vocabulary deliberately. It is expected that their tokens coverage increase to 98 in order to enable incidental learning.

The data from chapter I shows that most of the tokens 84.72, types 71.60 and word families 223 are found in GSL_1. It can be interpreted that
the chapter I provide general vocabulary that students are common with. Moreover, this chapter will be easy to understand. Chapter I provides big portion
to learn more vocabularies outside 1,000 most frequent English. It has 15.28 tokens, 28.4 types and 69 word families. Thus, it is expected that students have
opportunity to learn those tokens, types and word families. Chapter I has good learning proficiency because the students can learn easily and common word lists
and they can learn more vocabularies outside the list outside GSL_1.
As the beginning chapter, it is a good consideration to use a lot of words from GSL_1 and GSL_2 since it covers English words for general use. It also
helps students to recognize words listed in the 2,000 most frequent English words as the basis for their vocabulary knowledge. This chapter tends to be not too
difficult to understand since 94.85 of the tokens are listed in GSL_1 and GSL_2. This means that it might require less effort from students to read this
chapter independently assuming that students already recognize all tokens in GSL_1 and GSL_2. It is also a good decision to include words outside those
2,000 most frequent English words. Although words from the AWL and not in the list only show a small number, it gives students opportunity to reach higher level
of their current vocabulary size. 3. Vocabulary Coverage of Chapter II
